The sad and untimely death of Mr. .lames Murray, the marine hinlosiist of the expediticin, fulldwinj; the hiss of lie' Kiirhik. placed upon the shoulders of Mr. Frits .lohansen. to whom the eiitomoloiiical work lia his botanical ami entomological work. The larue collections of marine and other invertebrates, lishes, and plants testify as to the assiduity with which -M]'. .lohansen collected. Hut, as w;is inevitable the number of insects collected was less than wi> had oriirinally hoped to receive. Nevertheless, the collection of insects broudht b.tck by the expedition was a very represcnt.ativo one, and, a-- the succeedin<{ reports will show, it has been the means of adding valuable information to our kiiowledjfr of the insects of the northern rejiioiLs of this continent. No less than S new genera, iti? new species ami ."> new siib- six'cies and varieties have been deseiibed ill the followiiis; |)anes. In addition, as a result of .Mr. .JohansenV keen dsire to obtain notes on the life-histories and bionomics of tlws.> northern forms and the investiirations that he carried on under the diiliical aspect of an insect fauna, and reports become mere systematic cata- logues and lifeless. 'I'lie abundaiici' and variety of the arctic and sub-arctic insei't life will be suiprisinii perhaps to many entomolonists who have not hitherto appreciated the burst of pl.mt and insect life that takes place durinsi the short arc-tic summer when the land is clothed with veiietation and lloweis which are visited by innumerable bumble bees, moths and biitterilies and other sun-lovin(i insects, enjoying the brief spell of existence that nlease from the gelid land and water permits. We desire to cxpi'e.ss our warm appreciation of the assistanct so willingly rendered by the authors rthose names appear on the ditTerent reports in this volume in working i.' ' this interesting collection of the insects of the arctic and sub-an-tic region of North .Vmcric.-i, and we hope t litit this volume may stimulati further investigation of a fauna of intt rest alike ! i the systematist and to those who arc interested iti the broader <|Uestion of the distribution of animal life. < 1 1 1 \ w A, .lanuarv, 1(120.
